We have our first camp causality of the summer- and it might be a sign of another one coming soon.

The Eagles claimed running back William Powell from the Arizona Cardinals on Wednesday and released wide receiver Nick Miller.

"He studied (Powell) in the preseason last year," said general manager Howie Roseman said. "Hes quick, tough, has good hands. He is a guy we thought could upgrade the competition level at the position."

It's hard to imagine the decision to release Powell had nothing to do with the fact that rookie running back Matthew Tucker failed his conditioning test on Monday.

Tucker has been unable to practice with the team so far, instead his days at camp have been spent practicing for his second attempt at a conditioning test. If he fails the test on Thursdays, it's hard to imagine he will be given a third shot.

"You gotta be able to pass the conditioning test" Roseman said when asked about Tucker.

Powell, who will arrive in Philadelphia on Thursday, comes to the Eagles after spending one season in Arizona. The 2nd year player has 60 career carries for 217 yards.

The fact that the team cut Murphy and picked up a running back is definitely a warning shot to Tucker. It also means that they like him enough to give him a second shot, however, something that most undrafted rookies are not given the luxury of getting.
